to investigate the reasons behind the crash and submit its findings by 31 August 2010, a deadline later extended by a month to 30 September 2010. The government also appointed four experts to this court of inquiry to assist in the investigation. The Court of Inquiry started its investigations by visiting the crash site on 7 June 2010, and visited all eight crash survivors to gather information.

The CVR analysis revealed that one of the pilots was asleep in the cockpit. For 110 minutes, the CVR had picked up no conversation from the pilots, with the report adding that the sound of nasal snoring and deep breathing could be heard during this recording. The FDR analysis indicated that the flight started its final descent at an altitude of , instead of the normal . The aircraft also touched down at the mark on the runway instead of the mark, whereupon the pilot
